8-8x<3x-8-2
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 2-2x.
8-8x<3x-10
Tangohia te 2 i te -8, ka -10.
8-8x-3x<-10
Tangohia te 3x mai i ngā taha e rua.
8-11x<-10
Pahekotia te -8x me -3x, ka -11x.
-11x<-10-8
Tangohia te 8 mai i ngā taha e rua.
-11x<-18
Tangohia te 8 i te -10, ka -18.
x>\frac{-18}{-11}
Whakawehea ngā taha e rua ki te -11. I te mea he tōraro a -11, ka huri te ahunga koreōrite.
x>\frac{18}{11}
Ka taea te hautanga \frac{-18}{-11} te whakamāmā ki te \frac{18}{11} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
